Ocean station data collected using bottle casts from the ALMIRANTE SALDANHA in the South Atlantic Ocean from 1984-02-19 to 1984-03-26 (NODC Accession 9000034)

Ocean station data were collected using seechi disk, meteorological sensors, and bottle casts in the South Atlantic Ocean from 19 February 1984 to 26 March 1984. The physical profile data was collected using ALMIRANTE SALDANHA by the Directoria de Hidrografia e Navagacao in Brazil. The data was submitted in GF-3 format and has been processed by NODC. The data is currently available in the NODC C100 Ocean Station Data file format. The C100 format is used for physical-chemical oceanographic data recorded at discrete depth levels. Most of the observations were made using multi- bottle Nansen casts or other types of water samplers. A small amount (about 5%) were obtained using electronic CTD (conductivity-temperature-depth) or STD (salinity-temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information, position, date and time are reported for each station. Each station contains the measurements taken at observed depth levels, but also includes data values interpolated to a set of standard depth levels.1984年2月19日至1984年3月26日，科研团队于南大西洋海域采用赛氏盘（Secchi disk）、气象传感器与采水器采样的方式获取海洋站数据。海洋物理剖面数据由巴西水文与航海总局（Directoria de Hidrografia e Navagacao）搭载“阿尔米兰特·萨尔达尼亚号”（ALMIRANTE SALDANHA）科考船采集完成。该数据集以GF-3格式提交，并已由国家海洋数据中心（National Oceanographic Data Center，NODC）完成预处理与标准化处理。当前该数据集以NODC C100海洋站数据文件格式对外共享。 C100格式专用于记录离散深度层的物理化学海洋学观测数据。本次数据集的多数观测采用多瓶南森采水器（multi-bottle Nansen casts）或其他类型水体采样器完成；仅约5%的少量数据通过电子电导率-温度-深度（CTD，conductivity-temperature-depth）或盐度-温度-深度（STD，salinity-temperature-depth）记录仪获取。需说明的是，CTD/STD数据以与南森采水器采样数据一致的深度层级上报至NODC，其后续处理与存储流程与南森采水器数据完全一致。每个观测站位均附带航次信息、站位坐标、观测日期与时间参数；每个站位不仅包含实测深度层的原始观测数据，还包含经插值得到的标准化深度层数据集。
